Description

Technical Field

[0001] This disclosure relates to the field of ultrasonic cleaning technology, and more specifically, to pressurized equipment. Background Technology

[0002] Filtration equipment is widely used in many industrial fields such as chemical, pharmaceutical, electronics and machinery. The performance and cleanliness of its core component - the filter element - directly determine the working efficiency and filtration effect of the filtration equipment.

[0003] In related technologies, filter elements are mainly cleaned using methods such as backflushing and backwashing. While these methods are simple to operate, their cleaning effect is not ideal when dealing with thick or sticky impurities adhering to the filter element surface. Moreover, when the cleaning medium bypasses parts of the filter element during the cleaning process, it is impossible to achieve overall online cleaning of the filter element, and it must be disassembled for offline cleaning. In this case, it is not only time-consuming and labor-intensive, but may also cause secondary contamination of the filter element.

[0004] Ultrasonic cleaning technology, as a highly efficient cleaning method, works by using a high-frequency oscillation signal emitted by an ultrasonic generator. This signal is converted into high-frequency mechanical vibration by an ultrasonic transducer and propagates into the cleaning medium. The instantaneous high pressure and shock waves generated by the cavitation effect then achieve efficient cleaning of the surface of the workpiece. However, most existing ultrasonic cleaning devices are suitable for open, pressureless, non-corrosive, or slightly corrosive environments, making it difficult to meet the online cleaning needs of filter elements within pressurized filtration equipment.

[0005] Therefore, how to apply ultrasonic cleaning technology to the online cleaning of filter elements in pressurized filtration equipment is a technical problem that urgently needs to be solved. Summary of the Invention

[0006] This section provides a general overview of this disclosure, rather than a full disclosure of the entire scope or all features of this disclosure.

[0007] According to an embodiment of this disclosure, a pressurized device is provided. The pressurized device includes a housing and an ultrasonic cleaning apparatus. A chamber is formed inside the housing. The ultrasonic cleaning apparatus is disposed inside the chamber to perform ultrasonic cleaning on a workpiece to be cleaned within the chamber. The ultrasonic cleaning apparatus includes a first cleaning component and a first sealing structure. The first cleaning component includes an ultrasonic transducer element for emitting ultrasonic waves. The first sealing structure forms a first sealed space to accommodate the first cleaning component therein.

[0008] According to the above technical solution, by directly placing the first cleaning assembly, including the ultrasonic transducer, within the chamber of the pressurized equipment, and by housing the first cleaning assembly within the first sealed space formed by the first sealed structure, damage to the ultrasonic transducer caused by contact between the ultrasonic transducer and the cleaning medium during cleaning or with the fluid in the filtration equipment during filtration is avoided. Furthermore, damage to the ultrasonic transducer caused by the pressure within the pressurized chamber of the pressurized equipment is also avoided. Therefore, it is not necessary to remove the workpiece from the pressurized equipment; instead, the workpiece can be cleaned directly within the pressurized chamber of the pressurized equipment, thereby achieving online cleaning of the workpiece within the pressurized equipment using ultrasonic cleaning technology.

[0029] The technical solutions in this disclosure will now be clearly and completely described with reference to the accompanying drawings.

[0030] In ultrasonic cleaning technologies, external ultrasonic cleaning devices are typically used. Specifically, this type of device mounts the ultrasonic transducer on the outer periphery of the cleaning tank, ensuring it is in close contact with the tank's outer wall. During the ultrasonic cleaning process, the vibration of the ultrasonic transducer causes the cleaning medium within the tank to oscillate at high frequency. This high-frequency oscillation creates numerous microbubbles in the cleaning medium. These microbubbles expand and burst under the influence of the ultrasonic waves, generating a "cavitation effect," thereby achieving highly efficient cleaning of the surface of the workpiece.

[0031] External ultrasonic cleaning devices are typically suitable for open, unpressurized, non-corrosive, or mildly corrosive environments. However, in actual cleaning processes, many scenarios require operation under closed, pressurized, high-temperature, and highly corrosive conditions. This places higher demands on the sealing, pressure resistance, and corrosion resistance of ultrasonic cleaning devices. In particular, ultrasonic transducers, as electronic components, must avoid contact with flammable, explosive, or corrosive gases or liquids during use, and external ultrasonic cleaning devices often fail to meet these requirements.

[0032] Based on this, see Figure 1 This illustrates a pressurized device 1 provided in an embodiment of the present disclosure.

[0033] The pressurized equipment 1 includes a housing 10, within which a chamber 100 is formed. The pressurized equipment 1 also includes an ultrasonic cleaning device 20 disposed within the chamber 100 for cleaning the workpiece 30 (see [link to ultrasonic cleaning device]) within the chamber 100. Figure 3 Ultrasonic cleaning is performed.

[0034] The ultrasonic cleaning device 20 includes a first cleaning component 210 and a first sealed structure 220. The first cleaning component 210 (in...) Figure 1 (Shown in shaded area) Includes an ultrasonic transducer element (not shown) for emitting ultrasonic waves. A first enclosed structure 220 forms a first enclosed space 2201 to house the first cleaning assembly 210 therein.

[0035] In some examples, the pressurized device 1 can be a filtration device, and the part 30 to be cleaned can be a filter element disposed within the chamber of the filtration device to filter the fluid within the chamber. The pressurized device 1 provided in this disclosure is not limited to a filtration device, but can also be applied to other pressurized industrial equipment, such as chemical reaction vessels. For the sake of brevity and clarity in the following description, a filtration device is used as an example to illustrate the technical solution in this disclosure.

[0036] During the cleaning process, the ultrasonic transducer is used to convert the high-frequency oscillation signal emitted by the ultrasonic generator into high-frequency mechanical oscillation, which is then transmitted into the cleaning medium to perform ultrasonic cleaning on the workpiece.

[0037] The first enclosed space 2201 formed by the first enclosed structure 220 provides installation space for structures such as the first cleaning component 210.

[0038] The fluid to be filtered is typically a liquid or a gas, and the cleaning medium during the cleaning process is usually a liquid. This fluid or cleaning medium may possess flammable, explosive, or corrosive properties. Therefore, by installing the first cleaning assembly 210, which includes an ultrasonic transducer, into the first enclosed space, direct contact between the ultrasonic transducer and the cleaning medium or the fluid to be filtered can be avoided, preventing direct damage to the ultrasonic transducer and also preventing the possibility of combustion or explosion.

[0039] Furthermore, since the chamber 100 is pressurized, by installing the first cleaning assembly 210 into the first sealed space 2201, it is possible to prevent the ultrasonic transducer element of the first cleaning assembly 210 from being damaged by the pressure inside the pressurized chamber 100.

[0040] In this way, the component to be cleaned can be cleaned directly in the pressurized chamber 100 without disassembling it, thus realizing online cleaning of components such as filter elements.

[0041] In some possible implementations, the first sealing structure 220 is connected to the inner wall 100a of the chamber 100.

[0042] The connections here include both direct and indirect connections. For example, such as... Figure 2 and Figure 11 As shown, the first sealing structure 220 can be directly fixed to the inner wall 100a of the chamber 100 to directly achieve the connection between the first sealing structure 220 and the inner wall 100a. Or, as... Figure 5 and Figure 14 As shown, the first sealing structure 220 can be directly fixed to the fixing structure 11 for installing the filter element (e.g., the filter disc for installing the filter element), and the fixing structure 11 is fixed to the inner wall 100a of the chamber 100, thereby indirectly realizing the connection between the first sealing structure 220 and the inner wall 100a.

[0043] In this way, the inner wall 100a can provide support for the first sealed structure 220 and resist the impact force generated by the cleaning medium during the cleaning process or the fluid to be filtered during the filtration process on the first sealed structure 220.

[0044] In some possible implementations, such as Figures 1 to 3 As shown, the pressurized device 1 also includes a second sealing structure 40, which connects the first sealing structure 220 to the inner wall 100a to form a second sealed space 401 between the first sealing structure 220 and the inner wall 100a.

[0045] In this way, the first sealed structure 220 can be more firmly fixed to the inner wall 100a, thereby improving its resistance to the impact force exerted by the cleaning medium during the cleaning process or the fluid to be filtered during the filtration process. Moreover, since the second sealed space 401 is located between the first sealed structure 220 and the inner wall 100a, it can also provide additional protection for the first sealed structure 220 and, consequently, the first cleaning assembly 210 within the first sealed structure 220, to prevent the ultrasonic transducer element of the first cleaning assembly 210 from being affected by accidental impacts applied to the housing 10 from the outside.

[0046] In some possible implementations, such as Figure 2 As shown, the pressurized device 1 also includes a first support member 50, which is disposed in the second enclosed space 401 and between the inner wall 100a and the first enclosed structure 220 to support the first enclosed structure 220.

[0047] When a second sealed space 401 is formed between the first sealed structure 220 and the inner wall 100a, one side of the first sealed structure 220 will be in contact with a fluid (such as cleaning fluid or fluid to be filtered) and thus be subjected to internal pressure; while the other side will be in the second sealed space 401 without fluid and thus be subjected to atmospheric pressure. For example, in Figure 2 In this configuration, the radially inner side of the first sealed structure 220 is in contact with the fluid, while the radially outer side is in the second sealed space 401 where there is no fluid. This creates a pressure difference between the two sides of the first sealed structure 220, potentially leading to deformation or damage to the first sealed structure 220.

[0048] By providing a first support member 50 in the second enclosed space 401 to support the first enclosed structure 220, the possibility of deformation of the first enclosed structure 220 can be reduced, thereby better protecting the first cleaning component 210 housed in the first enclosed structure 220 and improving the stability of the entire system operation.

[0049] Furthermore, it is conceivable that the first support member 50 may also be connected in the axial direction of the chamber 100 to the third fixing portion 204 and the fourth fixing portion 205, which will be described below (see Figure 1 ( ) contact, to provide support for the third fixed part 204 and the fourth fixed part 205.

[0050] In some examples, the first support member 50 may be a structural member such as an angle steel or a stiffening plate, but is not limited to this.

[0051] In some possible implementations, such as Figure 1 and Figure 2As shown, the housing 10 has a pressure-stabilizing medium inlet 10a, which is connected to the second sealed space 401 to fill the second sealed space 401 with a pressure-stabilizing medium.

[0052] In this situation, the pressure difference between the two sides of the first sealed structure 220 can be adjusted by filling the second sealed space 401 with a pressure-stabilizing medium from the pressure-stabilizing medium inlet 10a, so that the pressure difference is kept within a preset range. This also reduces the possibility of deformation of the first sealed structure 220, thereby better protecting the first cleaning component 210 housed within the first sealed structure 220 and improving the stability of the entire system operation.

[0053] In some examples, the aforementioned stabilizing medium is either a gas or a liquid, depending on the specific circumstances.

[0054] In some possible implementations, refer to Figures 1 to 5 The first sealing structure 220 is configured to enclose the central axis X of the chamber 100 (see Figure 1 ).

[0055] In this configuration, the first sealed structure 220 is arranged in a ring around the central axis X of the chamber 100 to ensure that the emitted ultrasonic waves are evenly distributed in all areas of the chamber 100, thereby reducing dead zones in ultrasonic cleaning and improving the cleaning effect.

[0056] It is conceivable that when the first enclosed structure 220 is configured to be arranged enclosedly around the central axis X of the chamber 100, a plurality of first cleaning components 210 can be provided in the first enclosed structure 220. In some examples, the plurality of first cleaning components 210 are also arranged around the central axis X of the chamber 100.

[0057] See Figure 4 and Figure 5 In some embodiments described above, the first sealing structure 220 includes a first fixing portion 202 and a second fixing portion 203, which are arranged in the radial direction of the chamber 100 to define a first sealing space 2201 between the first fixing portion 202 and the second fixing portion 203. For example... Figure 5 As shown, the first sealing structure 220 can be directly fixed to the fixing structure 11 for mounting the filter element 30, for example.

[0058] The first fixing part 202, when viewed from the outside, is a prism with a polygonal cross-sectional shape. Furthermore, the first fixing part 202 can be a one-piece molded structure or composed of multiple sides joined together by welding or other methods. The second fixing part 203, when viewed from the outside, is also a prism with a polygonal cross-sectional shape. For ease of installation, the second fixing part 203 can be composed of multiple sides joined together by welding or other methods.

[0059] Furthermore, the first fixing portion 202 and the second fixing portion 203 include the same number of sides, for example in Figure 4 When viewed from the outside, the first fixing part 202 and the second fixing part 203 are both prisms with a hexagonal cross-section, which together define a first enclosed space 2201 for accommodating the first cleaning assembly 210.

[0060] It should be noted that the number of sides in the first fixing part 202 and the second fixing part 203 is not limited to... Figure 4 The six shown can be adjusted according to actual conditions. Optionally, the number of sides of the first fixing part 202 can be set from three to ten. This is because increasing the number of sides allows the cross-sectional shape of the first fixing part 202 to approach a circle, thereby increasing the flow volume of the fluid during filtration and thus improving the filtration capacity of the filtration equipment. However, a greater number of sides requires more connection points, significantly increasing the requirements for processing precision and assembly technology. Moreover, too many connection points can easily form stress concentration points, reducing the operational stability of the filtration equipment. In addition, increasing the number of connection points may also cause leakage of the cleaning medium, leading to damage to the ultrasonic transducer element.

[0061] In some embodiments described above, a support member may also be provided between the inner wall 100a of the chamber 100 and one of the first fixing portion 202 and the second fixing portion 203 that is closer to the inner wall 100a.

[0062] The support member can provide rigid support for the first sealed structure 220 in the radial direction of the chamber 100, thereby enabling the first sealed structure 220 to be stably fixed in the chamber 100.

[0063] In some examples, at least one support member may be provided between each side or part of the side of one of the first fixing portion 202 and the second fixing portion 203 and the inner wall 100a. Multiple supports may also be provided in the height direction of one of the components to enhance support strength.

[0064] In some examples, the support can be a structural component such as angle steel or stiffening plate, but it is not limited to these.

[0065] In some examples of the above implementation methods, such as Figures 1 to 3 As shown, the first sealed space 2201 is formed by a first fixed part 202, a second fixed part 203, a third fixed part 204, and a fourth fixed part 205. The first fixed part 202 and the second fixed part 203 are arranged in the radial direction of the chamber 100, and the third fixed part 204 and the fourth fixed part 205 are arranged in the axial direction of the chamber 100. The second sealed space 401 is formed by the first fixed part 202 and the second fixed part 203 that are close to the inner wall 100a of the chamber 100, the third fixed part 204, the fourth fixed part 205, and the inner wall 100a of the chamber 100.

[0066] In this way, the first sealing structure 220 can be effectively fixed to the inner wall 100a with a simple structure, and the fixation is firm and stable.

[0067] It is conceivable that, in the example above, such as Figures 1 to 3 As shown, the pressurized device 1 also includes a second support member 60, which is connected between the third fixing part 204 and the fourth fixing part 205.

[0068] In this case, the second support member 60 can provide rigid support to the third fixed part 204 and the fourth fixed part 205 in the axial direction of the chamber 100, thereby providing rigid support to the first sealed structure 220 and improving the bending strength of the first sealed structure 220.

[0069] Moreover, it is conceivable that the second support member 60 is connected to at least one of the first fixed part 202 and the second fixed part 203, so that the second support member 60 can also provide rigid support to the first sealed structure 220 in the radial direction of the chamber 100, thereby enhancing the ability of the first sealed structure 220 to resist deformation.

[0070] In some implementations, such as Figure 6 As shown, the ultrasonic transducer can emit ultrasonic waves toward opposite sides of the first sealed structure 220 in the radial direction of the chamber 100 (schematically shown with dashed arrows).

[0071] This method achieves bidirectional cleaning. This bidirectional cleaning approach allows for a more uniform distribution of ultrasonic energy within the cleaning area, effectively avoiding areas of concentrated or weak energy during the cleaning process. Therefore, the ultrasonic energy distribution within the cleaning area is more balanced, reducing blind spots and ensuring that all parts of the surface to be cleaned receive sufficient ultrasonic energy, resulting in a more comprehensive and efficient cleaning effect.

[0072] It is conceivable that during the bidirectional cleaning process, the parts to be cleaned are located on the inner and outer sides of the first cleaning assembly 210 in the radial direction of the chamber 100. However, even... Figure 2 In such cases, it is understandable that the ultrasonic transducer element emits ultrasonic waves to the opposite sides of the first sealed structure 220, and this solution does not restrict this.

[0073] In some examples of the above-described embodiments, to improve the cleaning effect on the parts to be cleaned located in the central region of chamber 100, such as... Figures 7 to 9 As shown, the ultrasonic cleaning device 20 also includes a second cleaning component 230 and a third sealed structure 240.

[0074] The second cleaning assembly 230 includes an ultrasonic transducer element for emitting ultrasonic waves. A third sealing structure 240 is used to form a third sealed space 2401 to house the second cleaning assembly 230 therein, and in the radial direction of the chamber 100, the third sealed space 2401 is located inside the first sealed space 2201.

[0075] Reference Figure 7 and Figure 9 The third sealed structure 240 can be directly fixed to the fixing structure 11 for mounting the filter element 30, for example.

[0076] In some examples, there is no specific limitation on the number of second cleaning components 230 contained in the third enclosure 240, which may be the same as or different from the number of first cleaning components 210 contained in the first enclosure 220.

[0077] In the specific implementation process, such as Figure 10 As shown, the ultrasonic cleaning device 20 also includes a support member 900 and a support part 1000, wherein the support member 900 is fixedly disposed on the central axis of the chamber 100, and the support part 1000 is disposed between the support member 900 and the third sealing structure 240.

[0078] In some examples, the support 1000 includes a support column 1001 and a connecting plate 1002. In specific implementations, multiple layers of connecting plates 1002 can be stacked along the height direction of the third enclosed structure 240 to provide sufficient rigid support for the third enclosed structure 240. The number of layers of connecting plates 1002 can be determined according to the actual situation.

[0079] In some possible implementations, such as Figure 11 and Figure 12As shown, the ultrasonic cleaning device 20 includes a plurality of first sealing structures 220, each of which is arranged along a plurality of different radial directions of the chamber 100, and the outer surface of the ultrasonic waves emitted by each first sealing structure 220 extends parallel to the corresponding radial direction of the chamber 100.

[0080] In this case, the cleaning effect can be achieved within the limited space of the chamber 100.

[0081] It is conceivable that each first sealing structure may include multiple sub-sealing structures, each of which may also include a sealed space, and each may house the first cleaning component therein. These sub-sealing structures may be arranged in the radial direction or the axial direction of the chamber 100, without limitation.

[0082] Figures 11 to 13 An embodiment is shown in which the first sealing structure 220 is directly fixed to the inner wall 100a of the chamber 100. Figure 14 and Figure 15 An embodiment is shown in which the first sealing structure 220 is spaced apart from the inner wall 100a and indirectly connected to the inner wall 100a by being fixed to the fixing structure 11. Figure 16 and Figure 17 This illustrates an embodiment in which a second sealed space 401 exists between the first sealed structure 220 and the inner wall 100a.

[0083] Reference Figures 11 to 15 In some examples, the first sealing structure 220 includes a first fixing portion 202, a second fixing portion 203, a fifth fixing portion 206, and a sixth fixing portion 207. The first fixing portion 202 and the second fixing portion 203 are arranged in the radial direction of the chamber 100, and the fifth fixing portion 206 and the sixth fixing portion 207 are arranged in a direction perpendicular to the radial and axial directions of the chamber 100, so as to define a first sealing space 2201 therebetween.

[0084] like Figure 11 , Figure 13 and Figure 14 As shown, the first sealing structure 220 can also be fixed to the fixing structure 11 for mounting the filter element 30. In this case, the filter element 30 is located in the area between two adjacent first sealing structures 220.

[0085] Reference Figure 16 and Figure 17In some examples, the first enclosed space 2201 is enclosed by a first fixing part 202, a second fixing part 203, a third fixing part 204, a fourth fixing part 205, a fifth fixing part 206, and a sixth fixing part 207. The first fixing part 202 and the second fixing part 203 are arranged in the radial direction of the chamber 100, the third fixing part 204 and the fourth fixing part 205 are arranged in the axial direction of the chamber 100, and the fifth fixing part 206 and the sixth fixing part 207 are arranged in a direction perpendicular to the radial and axial directions of the chamber 100. The second enclosed space 401 is enclosed by the first fixing part 202 and the second fixing part 203 near the inner wall 100a of the chamber 100, the third fixing part 204, the fourth fixing part 205, the fifth fixing part 206, the sixth fixing part 207, and the inner wall 100a.

[0086] In this way, the first sealing structure 220 can be effectively fixed to the inner wall 100a with a simple structure, and the fixation is firm and stable.

[0087] In the presence of a second enclosed space 401, refer to Figure 18 Similarly, a first support member 50 can be provided in the second enclosed space 401 and between the inner wall 100a and the first enclosed structure 220; and / or a pressure-stabilizing medium inlet 10a communicating with the second enclosed space 401 can be opened on the housing 10. Further details will not be elaborated here.

[0088] For the above implementation methods, see, in some examples, for further details. Figure 11 , Figure 14 , Figure 16 and Figure 18 The pressurized device 1 also includes a third support member 70 and a plurality of fourth support members 80. The third support member 70 is arranged at the central axis X of the chamber 100, and the plurality of fourth support members 80 are connected between the third support member 70 and the inner wall 100a in correspondingly different radial directions of the chamber 100 to support the plurality of first sealing structures 220 from below.

[0089] In this way, rigid support can be provided to the first sealed structure 220 from below, so that the first sealed structure can be more stably fixed in the chamber 100.

[0090] It is conceivable that the fourth support member 80 can directly support the first sealed structure 220, or it can be like... Figure 11 As shown, the first enclosed structure 220 is supported by the lower support member 70a.

[0091] In some examples of the above implementation methods, reference is made to... Figure 15 and Figure 19Each first sealed structure 220 includes two opposite outer surfaces extending in a corresponding radial direction parallel to the chamber 100, and the ultrasonic transducer emits ultrasonic waves from at least one of the two opposite outer surfaces.

[0092] like Figure 15 As shown, when the ultrasonic waves emitted by the ultrasonic transducer element in the first cleaning assembly 210 exit from the two external surfaces, bidirectional cleaning is achieved. Figure 19 As shown, when the ultrasonic waves emitted by the ultrasonic transducer element in the first cleaning assembly 210 (schematically shown by dashed arrows) exit from only one external surface, unidirectional cleaning of a specific area can be achieved.

[0093] To achieve the aforementioned bidirectional cleaning, for example, as follows: Figure 15 As shown, when only one first cleaning assembly 210 is arranged in each first sealed structure 220, multiple ultrasonic transducers are arranged in the first cleaning assembly 210 along the radial direction of the chamber 100, and the ultrasonic waves emitted by two adjacent ultrasonic transducers have opposite emission directions.

[0094] Or, refer to Figure 20 As shown, when multiple first cleaning components 210 are arranged in each first sealed structure 220 along the radial direction of the chamber 100, the ultrasonic waves emitted by the ultrasonic transducers in two adjacent first cleaning components 210 (schematically shown by dashed arrows) have opposite emission directions. It is conceivable that two adjacent first cleaning components 210 are connected by a support member 210a.

[0095] It should be noted that the bidirectional cleaning method provided in this disclosure is not limited to the arrangement of the first cleaning component 210 described in the foregoing embodiments. In specific implementation, the arrangement of the first cleaning component 210 and its ultrasonic transducer can be adjusted according to the actual situation.

[0096] It should be noted that the number of the first cleaning components 210 can be set according to actual needs. However, if the number of the first cleaning components 210 is too large, it may occupy a large amount of space, affecting the available space of filter elements in the filtration equipment, and thus potentially reducing the filtration effect of the filtration equipment. Therefore, in specific implementation, the number of the first cleaning components 210 can be selected from 1 to 10, so as to meet the cleaning requirements while avoiding affecting the normal operation of the filtration equipment.

[0097] In some examples, such as Figure 1 and Figure 7 As shown, both the first cleaning component 210 and the second cleaning component 230 can be electrically connected to the controller 3 via a wire 2202.

[0098] like Figure 1 As shown, wire 2202 can be led out to controller 3 via cable conduit 2203. Furthermore, as... Figure 7 As shown, the wire 2202 can be led out to the controller 3 via the conduit 2203 of the first cleaning assembly 210 and the second cleaning assembly 230, respectively, or it can be collected in the chamber 100 and then led out to the controller 3. Figure 11 As shown, wire 2202 can be sequentially led out to controller 3 via lower support 70a and fourth support 80. It is understood that controller 3 is used to control the operating state of the ultrasonic transducer. It should be noted that the technical solutions described in this disclosure can be arbitrarily combined without conflict.

[0099] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
